so .. I already did follow mm's steps, just need to reboot but I still need to download a file so I just wait a bit as long as everything's still running
On a side note : I was using the same beta drivers on 12.04 a week ago and everything was running fine (except LoL which could've been because of Unity 3D), so I've been wondering now why it's not working on 13.10 (bugs, kernel, anything? I'm still not very experienced with Linux/Ubuntu but I'm figuring things out .. or atleast I try to)
Edit: sooo, I can tell something's not right .. or atleast I guess so
How I come to this conclusion .. well, I can't start Steam anymore, which was possible before, due to missing libraries

I don't know what to do, but then again I only followed your steps anyway, updating the Kernel (if that's what I've been doing), adding the repo, updating/upgrading and rebooting
